10.030.0631 Terra Cotta Lintel Repair, Hand Pressed TC


This detail is a modern repair solution of an original detail shown in Plate 36 of Terra Cotta Standard Construction published by the National Terra Cotta Society in 1927. This detail illustrates one method of repairing a terra cotta (TC) soffit, lintel, and facade units around a window opening. The TC veneer is supported by structural steel and brick masonry backing. TC facade units are held in place with stainless steel (SS) strap & pin anchors secured to the brick backing and engaged into the sidewalls of the TC units. Lintel units are hung on a continuous SS steel rod supported by threaded J-Hooks between the units. Each J-Hook is threaded at the top through one end of a tab anchor. The tabs are secured by threaded bolts through the flange of the steel channel. The original round anchor is not replaced. The steel is coated with a corrosion inhibitor. The TC units are typically left hollow. The TC soffit units are hung by two bent SS strap & pin anchors that engage through the TC sidewalls. The holes in the sidewalls are filled with sealant around the pin. The bent strap & pin anchors are secured through the back flange of the steel channel and ancillary steel plate. The soffit is left hollow similar to the lintel.

10.030.0633 Lintel rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) lintel, soffit, and accessory units around window openings. The existing TC is replaced with new extruded TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, and an integrated flashing system installed to protect existing structural steel. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. Accessible existing structural steel is also protected by cleaning and coating with a corrosion-inhibiting co

10.030.0433 Sill and mullion rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) sill, mullion, and accessory units around window openings. The existing TC is replaced with new extruded TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, and an integrated flashing system beneath the sill. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. The existing structural steel supports are also protected by cleaning and coating with a corrosion-inhibiting coating. These TC rebuild details

04.030.0202 Dimension stone wall, interior | Wire ties and molding plaster

     04.030.0202 Dimension stone wall, interior | Wire ties and molding plaster This detail shows 2 cm (3/4 in.) thick dimension stone anchored to an interior wall substrate with anchors of 8-gauge  (0.1285”) copper or stainless steel wire ties encapsulated by molding plaster at the perimeter of each stone panel. The wire is fitted into slightly oversized holes in edges of the stone panels, with wood plugs filling the space around the wire. The wire anchors are sized and spaced per empirical design and are fastened to the concrete masonry backing via holes cut into the block, also filled with plaster or rapid-curing cementitious material. Joints between the panels may be finished with compatible sealant and backer rod (not shown for clarity). This detail shall not be used for construction without the approval of a licensed design professional. The person using this detail shall be responsible for its complete design and proper application.
